I have a concept, but I have not been able to get it working on the NXPRapidIOT. I want to have an AWS DynamoDB table with three keys “Red”, “Green”, “Blue” all having boolean values. When I change the value of one of these keys, say “Red = True” in the AWSDynamoDB table, I want the RapidIOT RGB led to shine red. I am struggling in trying to find the correct (or just fuctional) way to allow asynchronous communications from AWS DynamoDB to the RapidIOT. I do not want to have the RapidIOT periodically polling the AWSDyanmoDB table to check for changes.
Here is the most recent description of my attempt…
I am trying to figure out how to allow an AWS DynamoDB trigger event act as an input to the NXPRapidIOT. My thought is that I would create an AWS Lambda function that would be executed by a DynamoDB trigger. The Lambda function would send a signal through a cloud element to the RapidIOT that indicating there has been a change to the database. The RapidIOT would then use cloud elements and AWSDynamoDB elements to pull the new data in from AWS.
Am I going down the wrong path in my approach?
